Hi! I’m Alice Johnson, here to help you with your FreeStyle Libre 3 app issue. I understand your app keeps crashing and won’t open on your device with Windows 10. Could you please tell me a bit more about this? For example:

- When did the app start crashing?
- Does it crash immediately when you open it or after some time?
- Have you tried any steps to fix it already, like restarting your device or reinstalling the app?

Knowing this will help me guide you better. In the meantime, I can share some common fixes that usually help with app crashes on similar devices.

Here are steps you can try:

1. Close the app completely and restart your PC: Sometimes a clean restart clears temporary glitches.
2. Check for app updates: Ensure you are running the latest version of the FreeStyle Libre 3 app as updates often fix bugs that cause crashes. You can do this via the Microsoft Store or the source you installed the app from.
3. Clear app cache and data (if possible on Windows version): Sometimes corrupted data cause crashes. On Windows apps, you can do this by:
- Open Settings
- Go to Apps & Features
- Find FreeStyle Libre 3 app, click it, and select Advanced options
- Click Reset to clear the app data
4. Make sure your Windows 10 OS is fully updated: Sometimes apps rely on system updates to function correctly.
5. Check network connection: The app might require stable internet or Bluetooth connection. Try turning Bluetooth off and on or switching your internet connection.
6. Reinstall the app: If none of the above works, uninstall and reinstall the app. Note that sometimes this can invalidate current sensor data, so please back up any critical info if possible.

If you’ve already tried some of these, please tell me which ones so I can suggest more advanced troubleshooting or escalate appropriately.

Does this help so far? Let me know about any details or what you have tried!
